Risks from injectable peptides
A Medical Xpress story summarises the risks associated with injectable peptides such as GHK-Cu, BPC-157 and TB-500, which are not approved for use in humans.

Animal studies suggest that these peptides increase the production of several growth factors and cytokines that are key drivers of arthrofibrosis and cancer. BP-157 has been banned by all regulatory authorities. These peptides may also impact brain chemistry and there are reports of mood dysregulation, flu-like symptoms and joint pain.
In my opinion, it is not wise to try injectable peptides, especially if you have arthrofibrosis.

A lack of health care provider knowledge about arthrofibrosis can make us desperate to find a remedy but we've got to be careful.
